The hurdle of developing a 3D Chess game is the minimum number of pieces
necessary to mate an opposing King.

Have you determined this condition?  Does your initial setup offer a
sufficient force?

Whereas two 2D Rooks can push a 2D King into a mate, it takes more than
four 3D Rooks to push a 3D King.  The addition of the triagonal slide to
the 3D Rook's normally orthogonal movement may improve this(BTW, this
piece is known as a Narwhal), but by what factor?

Even with the presence of a 3D Queen, how many other pieces would be
needed to force a mate?

I think you may find that your game will be quite draw-ish.  You may need
to adjust it to reduce this potential.  Might I be so bold as to ask if
you've consider the use of the Shogi capture-and-drop rules(and
maintaining the FIDE Pawn promotions).  This would definitely liven this
game and assure a player of sufficient pieces.

If you haven't done so, may I suggest that you join the following Yahoo!

Second Paragraph after blank line. Here is some HTML code mixed in with the Markdown, and here is the same <U>HTML code</U> enclosed by backticks.

Secondary Header: <H2>

  • Second unordered list item
  • New unordered list
    • Nested list item

Third Level header <H3>

  1. An ordered list item.
  2. A second ordered list item with the same number.
  3. A third ordered list item.
Here is some preformatted text.
  This line begins with some indentation.
    This begins with even more indentation.
And this line has no indentation.
